The invention relates to an assembly of two pieces of bodywork of plastics material, each piece having an edge (6, 8) for coming into contact with the edge of the other piece, the assembly being characterized in that the edge (6) of one of the pieces has a slot (10) while the edge (8) of the other piece has a tongue (13) extending from the other piece and suitable for penetrating in said slot, so as to cause an end portion (14) of said tongue to project beyond the slot, said tongue being pierced by a through orifice (13) situated in its end portion (14), the other piece being provided with a cotter (12) attached to said other piece by means of a deformable link (11) which enables said cotter to be engaged in the through orifice (13) of the tongue once the tongue has been inserted in the slot, thereby retaining the tongue in the slot.
1/ An assembly of two pieces of bodywork of plastics material, each piece having an edge (6, 8) for coming into contact with an edge of the other piece, the assembly being characterized in that the edge (6) of one of the pieces has a slot (10) while the edge (8) of the other piece has a tongue (13) extending from the other piece and suitable for penetrating into said slot, so as to cause an end portion (14) of said tongue to project beyond the slot, said tongue being pierced by a through orifice (13) situated in its end portion (14), the other piece being provided with a cotter (12) attached to said other piece by means of a deformable link (11) which enables said cotter to be engaged in the through orifice (13) of the tongue once the tongue has been inserted in the slot, thereby retaining the tongue in the slot.
2/ An assembly according to claim 1, characterized in that the connection connecting the cotter to the piece of bodywork which carries it begins in the vicinity of the slot (10) and is shaped to form a strap (11) suitable for being folded over so as to enable the cotter to penetrate into the through orifice in the tongue.
3/ An assembly according to claim 1 or claim 2, characterized in that the cotter (12) comprises an insertion head (20) of conical or prismatic shape enabling it to be guided during engagement in the through orifice, and a body (21) of smaller thickness situated downstream from its head (in the direction for insertion into the through orifice).
4/ An assembly according to any one of claims 1 to 3, in which each edge (6, 8) of a piece has a side face (6a, 8a) for making contact with the other edge, the assembly being characterized in that at least one of the pieces is provided with wedges (23) cooperating with the corresponding contact side face to form a corner for receiving the edge of the other piece.
5/ An assembly according to claim 4, characterized in that wedges (23) are arranged in a staggered configuration so as to avoid interfering with each other and they are offset towards the inside of the vehicle so as to pass behind the contact face (6a, 8a) of the other piece.
6/ An assembly according to claim 5, characterized in that the staggered wedges (23) are dimensioned on the two pieces of bodywork in such a manner that two adjacent wedges, each belonging to respective one of the pieces, lie close to each other when the two pieces are assembled together.
7/ An assembly according to any one of claims 4 to 6, characterized in that the wedges (23) are prismatic in shape, the small base lying at the end of the wedge, thereby facilitating the approach between the two pieces of bodywork by acting as positioning guides along said third direction.
8/ An assembly according to any one of claims 1 to 7, characterized in that the cotter (121) is provided with a stub (30) making it easier to insert into the through orifice of the tongue (13) by providing a bearing surface, said stub preferably extending parallel to the tongue when the cotter is inserted in the through orifice.
9/ An assembly according to any one of claims 1 to 8, characterized in that the two pieces of bodywork comprise firstly a bumper (1), and secondly a fender or a piece of fender trim (2).
